    Pancreatic cancer genomes reveal aberrations in axon guidance pathway genes (2012)
    Nature Publishing Group (NPG)

    Publication Date: 2012-10-30
    Description: Pancreatic cancer is a highly lethal malignancy with few effective therapies. We performed exome sequencing and copy number analysis to define genomic aberrations in a prospectively accrued clinical cohort (n = 142) of early (stage I and II) sporadic pancreatic ductal adenocarcinoma. Detailed analysis of 99 informative tumours identified substantial heterogeneity with 2,016 non-silent mutations and 1,628 copy-number variations. We define 16 significantly mutated genes, reaffirming known mutations (KRAS, TP53, CDKN2A, SMAD4, MLL3, TGFBR2, ARID1A and SF3B1), and uncover novel mutated genes including additional genes involved in chromatin modification (EPC1 and ARID2), DNA damage repair (ATM) and other mechanisms (ZIM2, MAP2K4, NALCN, SLC16A4 and MAGEA6). Integrative analysis with in vitro functional data and animal models provided supportive evidence for potential roles for these genetic aberrations in carcinogenesis. Pathway-based analysis of recurrently mutated genes recapitulated clustering in core signalling pathways in pancreatic ductal adenocarcinoma, and identified new mutated genes in each pathway. We also identified frequent and diverse somatic aberrations in genes described traditionally as embryonic regulators of axon guidance, particularly SLIT/ROBO signalling, which was also evident in murine Sleeping Beauty transposon-mediated somatic mutagenesis models of pancreatic cancer, providing further supportive evidence for the potential involvement of axon guidance genes in pancreatic carcinogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3530898/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3530898/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Biankin, Andrew V -- Waddell, Nicola -- Kassahn, Karin S -- Gingras, Marie-Claude -- Muthuswamy, Lakshmi B -- Johns, Amber L -- Miller, David K -- Wilson, Peter J -- Patch, Ann-Marie -- Wu, Jianmin -- Chang, David K -- Cowley, Mark J -- Gardiner, Brooke B -- Song, Sarah -- Harliwong, Ivon -- Idrisoglu, Senel -- Nourse, Craig -- Nourbakhsh, Ehsan -- Manning, Suzanne -- Wani, Shivangi -- Gongora, Milena -- Pajic, Marina -- Scarlett, Christopher J -- Gill, Anthony J -- Pinho, Andreia V -- Rooman, Ilse -- Anderson, Matthew -- Holmes, Oliver -- Leonard, Conrad -- Taylor, Darrin -- Wood, Scott -- Xu, Qinying -- Nones, Katia -- Fink, J Lynn -- Christ, Angelika -- Bruxner, Tim -- Cloonan, Nicole -- Kolle, Gabriel -- Newell, Felicity -- Pinese, Mark -- Mead, R Scott -- Humphris, Jeremy L -- Kaplan, Warren -- Jones, Marc D -- Colvin, Emily K -- Nagrial, Adnan M -- Humphrey, Emily S -- Chou, Angela -- Chin, Venessa T -- Chantrill, Lorraine A -- Mawson, Amanda -- Samra, Jaswinder S -- Kench, James G -- Lovell, Jessica A -- Daly, Roger J -- Merrett, Neil D -- Toon, Christopher -- Epari, Krishna -- Nguyen, Nam Q -- Barbour, Andrew -- Zeps, Nikolajs -- Australian Pancreatic Cancer Genome Initiative -- Kakkar, Nipun -- Zhao, Fengmei -- Wu, Yuan Qing -- Wang, Min -- Muzny, Donna M -- Fisher, William E -- Brunicardi, F Charles -- Hodges, Sally E -- Reid, Jeffrey G -- Drummond, Jennifer -- Chang, Kyle -- Han, Yi -- Lewis, Lora R -- Dinh, Huyen -- Buhay, Christian J -- Beck, Timothy -- Timms, Lee -- Sam, Michelle -- Begley, Kimberly -- Brown, Andrew -- Pai, Deepa -- Panchal, Ami -- Buchner, Nicholas -- De Borja, Richard -- Denroche, Robert E -- Yung, Christina K -- Serra, Stefano -- Onetto, Nicole -- Mukhopadhyay, Debabrata -- Tsao, Ming-Sound -- Shaw, Patricia A -- Petersen, Gloria M -- Gallinger, Steven -- Hruban, Ralph H -- Maitra, Anirban -- Iacobuzio-Donahue, Christine A -- Schulick, Richard D -- Wolfgang, Christopher L -- Morgan, Richard A -- Lawlor, Rita T -- Capelli, Paola -- Corbo, Vincenzo -- Scardoni, Maria -- Tortora, Giampaolo -- Tempero, Margaret A -- Mann, Karen M -- Jenkins, Nancy A -- Perez-Mancera, Pedro A -- Adams, David J -- Largaespada, David A -- Wessels, Lodewyk F A -- Rust, Alistair G -- Stein, Lincoln D -- Tuveson, David A -- Copeland, Neal G -- Musgrove, Elizabeth A -- Scarpa, Aldo -- Eshleman, James R -- Hudson, Thomas J -- Sutherland, Robert L -- Wheeler, David A -- Pearson, John V -- McPherson, John D -- Gibbs, Richard A -- Grimmond, Sean M -- 13031/Cancer Research UK/United Kingdom -- 2P50CA101955/CA/NCI NIH HHS/ -- P01CA134292/CA/NCI NIH HHS/ -- P50 CA101955/CA/NCI NIH HHS/ -- P50 CA102701/CA/NCI NIH HHS/ -- P50CA062924/CA/NCI NIH HHS/ -- R01 CA097075/CA/NCI NIH HHS/ -- R01 CA97075/CA/NCI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Cancer Research UK/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2012 Nov 15;491(7424):399-405. doi: 10.1038/nature11547.

    Seventy-five genetic loci influencing the human red blood cell (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-12-12
    Description: Anaemia is a chief determinant of global ill health, contributing to cognitive impairment, growth retardation and impaired physical capacity. To understand further the genetic factors influencing red blood cells, we carried out a genome-wide association study of haemoglobin concentration and related parameters in up to 135,367 individuals. Here we identify 75 independent genetic loci associated with one or more red blood cell phenotypes at P 〈 10(-8), which together explain 4-9% of the phenotypic variance per trait. Using expression quantitative trait loci and bioinformatic strategies, we identify 121 candidate genes enriched in functions relevant to red blood cell biology. The candidate genes are expressed preferentially in red blood cell precursors, and 43 have haematopoietic phenotypes in Mus musculus or Drosophila melanogaster. Through open-chromatin and coding-variant analyses we identify potential causal genetic variants at 41 loci. Our findings provide extensive new insights into genetic mechanisms and biological pathways controlling red blood cell formation and function.〈br /〉〈br /〉〈a

    An anatomically comprehensive atlas of the adult human brain transcriptome (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-09-22
    Description: Neuroanatomically precise, genome-wide maps of transcript distributions are critical resources to complement genomic sequence data and to correlate functional and genetic brain architecture. Here we describe the generation and analysis of a transcriptional atlas of the adult human brain, comprising extensive histological analysis and comprehensive microarray profiling of approximately 900 neuroanatomically precise subdivisions in two individuals. Transcriptional regulation varies enormously by anatomical location, with different regions and their constituent cell types displaying robust molecular signatures that are highly conserved between individuals. Analysis of differential gene expression and gene co-expression relationships demonstrates that brain-wide variation strongly reflects the distributions of major cell classes such as neurons, oligodendrocytes, astrocytes and microglia. Local neighbourhood relationships between fine anatomical subdivisions are associated with discrete neuronal subtypes and genes involved with synaptic transmission. The neocortex displays a relatively homogeneous transcriptional pattern, but with distinct features associated selectively with primary sensorimotor cortices and with enriched frontal lobe expression. Notably, the spatial topography of the neocortex is strongly reflected in its molecular topography-the closer two cortical regions, the more similar their transcriptomes. This freely accessible online data resource forms a high-resolution transcriptional baseline for neurogenetic studies of normal and abnormal human brain function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4243026/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4243026/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hawrylycz, Michael J -- Lein, Ed S -- Guillozet-Bongaarts, Angela L -- Shen, Elaine H -- Ng, Lydia -- Miller, Jeremy A -- van de Lagemaat, Louie N -- Smith, Kimberly A -- Ebbert, Amanda -- Riley, Zackery L -- Abajian, Chris -- Beckmann, Christian F -- Bernard, Amy -- Bertagnolli, Darren -- Boe, Andrew F -- Cartagena, Preston M -- Chakravarty, M Mallar -- Chapin, Mike -- Chong, Jimmy -- Dalley, Rachel A -- Daly, Barry David -- Dang, Chinh -- Datta, Suvro -- Dee, Nick -- Dolbeare, Tim A -- Faber, Vance -- Feng, David -- Fowler, David R -- Goldy, Jeff -- Gregor, Benjamin W -- Haradon, Zeb -- Haynor, David R -- Hohmann, John G -- Horvath, Steve -- Howard, Robert E -- Jeromin, Andreas -- Jochim, Jayson M -- Kinnunen, Marty -- Lau, Christopher -- Lazarz, Evan T -- Lee, Changkyu -- Lemon, Tracy A -- Li, Ling -- Li, Yang -- Morris, John A -- Overly, Caroline C -- Parker, Patrick D -- Parry, Sheana E -- Reding, Melissa -- Royall, Joshua J -- Schulkin, Jay -- Sequeira, Pedro Adolfo -- Slaughterbeck, Clifford R -- Smith, Simon C -- Sodt, Andy J -- Sunkin, Susan M -- Swanson, Beryl E -- Vawter, Marquis P -- Williams, Derric -- Wohnoutka, Paul -- Zielke, H Ronald -- Geschwind, Daniel H -- Hof, Patrick R -- Smith, Stephen M -- Koch, Christof -- Grant, Seth G N -- Jones, Allan R -- 066717/Wellcome Trust/United Kingdom -- 077155/Wellcome Trust/United Kingdom -- 1C76HF15069-01-00/PHS HHS/ -- 1C76HF19619-01-00/PHS HHS/ -- G0700399/Medical Research Council/United Kingdom -- G0802238/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2012 Sep 20;489(7416):391-9. doi: 10.1038/nature11405.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Allen Institute for Brain Science, Seattle, Washington 98103, USA. mikeh@alleninstitute.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22996553" target="_blank"〉PubMed〈/a〉

    Mutations in DMRT3 affect locomotion in horses and spinal circuit function in mice (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-08-31
    Description: Locomotion in mammals relies on a central pattern-generating circuitry of spinal interneurons established during development that coordinates limb movement. These networks produce left-right alternation of limbs as well as coordinated activation of flexor and extensor muscles. Here we show that a premature stop codon in the DMRT3 gene has a major effect on the pattern of locomotion in horses. The mutation is permissive for the ability to perform alternate gaits and has a favourable effect on harness racing performance. Examination of wild-type and Dmrt3-null mice demonstrates that Dmrt3 is expressed in the dI6 subdivision of spinal cord neurons, takes part in neuronal specification within this subdivision, and is critical for the normal development of a coordinated locomotor network controlling limb movements. Our discovery positions Dmrt3 in a pivotal role for configuring the spinal circuits controlling stride in vertebrates. The DMRT3 mutation has had a major effect on the diversification of the domestic horse, as the altered gait characteristics of a number of breeds apparently require this mutation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3523687/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3523687/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Andersson, Lisa S -- Larhammar, Martin -- Memic, Fatima -- Wootz, Hanna -- Schwochow, Doreen -- Rubin, Carl-Johan -- Patra, Kalicharan -- Arnason, Thorvaldur -- Wellbring, Lisbeth -- Hjalm, Goran -- Imsland, Freyja -- Petersen, Jessica L -- McCue, Molly E -- Mickelson, James R -- Cothran, Gus -- Ahituv, Nadav -- Roepstorff, Lars -- Mikko, Sofia -- Vallstedt, Anna -- Lindgren, Gabriella -- Andersson, Leif -- Kullander, Klas -- R01 HD059862/HD/NICHD NIH HHS/ -- R01HD059862/HD/NICHD NIH HHS/ -- England -- Nature. 2012 Aug 30;488(7413):642-6. doi: 10.1038/nature11399.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Animal Breeding and Genetics, Swedish University of Agricultural Sciences, SE-75124 Uppsala, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22932389" target="_blank"〉PubMed〈/a〉

    Compensatory dendritic cell development mediated by BATF-IRF interactions (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-09-21
    Description: The AP1 transcription factor Batf3 is required for homeostatic development of CD8alpha(+) classical dendritic cells that prime CD8 T-cell responses against intracellular pathogens. Here we identify an alternative, Batf3-independent pathway in mice for CD8alpha(+) dendritic cell development operating during infection with intracellular pathogens and mediated by the cytokines interleukin (IL)-12 and interferon-gamma. This alternative pathway results from molecular compensation for Batf3 provided by the related AP1 factors Batf, which also functions in T and B cells, and Batf2 induced by cytokines in response to infection. Reciprocally, physiological compensation between Batf and Batf3 also occurs in T cells for expression of IL-10 and CTLA4. Compensation among BATF factors is based on the shared capacity of their leucine zipper domains to interact with non-AP1 factors such as IRF4 and IRF8 to mediate cooperative gene activation. Conceivably, manipulating this alternative pathway of dendritic cell development could be of value in augmenting immune responses to vaccines.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3482832/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3482832/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tussiwand, Roxane -- Lee, Wan-Ling -- Murphy, Theresa L -- Mashayekhi, Mona -- KC, Wumesh -- Albring, Jorn C -- Satpathy, Ansuman T -- Rotondo, Jeffrey A -- Edelson, Brian T -- Kretzer, Nicole M -- Wu, Xiaodi -- Weiss, Leslie A -- Glasmacher, Elke -- Li, Peng -- Liao, Wei -- Behnke, Michael -- Lam, Samuel S K -- Aurthur, Cora T -- Leonard, Warren J -- Singh, Harinder -- Stallings, Christina L -- Sibley, L David -- Schreiber, Robert D -- Murphy, Kenneth M -- AI076427-02/AI/NIAID NIH HHS/ -- P30 CA91842/CA/NCI NIH HHS/ -- R01 AI036629/AI/NIAID NIH HHS/ -- R01 AI076427/AI/NIAID NIH HHS/ -- R01 CA043059/CA/NCI NIH HHS/ -- T32 AI007163/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 Oct 25;490(7421):502-7. doi: 10.1038/nature11531.

    The deubiquitinase USP9X suppresses pancreatic ductal adenocarcinoma (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-06-16
    Description: Pancreatic ductal adenocarcinoma (PDA) remains a lethal malignancy despite much progress concerning its molecular characterization. PDA tumours harbour four signature somatic mutations in addition to numerous lower frequency genetic events of uncertain significance. Here we use Sleeping Beauty (SB) transposon-mediated insertional mutagenesis in a mouse model of pancreatic ductal preneoplasia to identify genes that cooperate with oncogenic Kras(G12D) to accelerate tumorigenesis and promote progression. Our screen revealed new candidate genes for PDA and confirmed the importance of many genes and pathways previously implicated in human PDA. The most commonly mutated gene was the X-linked deubiquitinase Usp9x, which was inactivated in over 50% of the tumours. Although previous work had attributed a pro-survival role to USP9X in human neoplasia, we found instead that loss of Usp9x enhances transformation and protects pancreatic cancer cells from anoikis. Clinically, low USP9X protein and messenger RNA expression in PDA correlates with poor survival after surgery, and USP9X levels are inversely associated with metastatic burden in advanced disease. Furthermore, chromatin modulation with trichostatin A or 5-aza-2'-deoxycytidine elevates USP9X expression in human PDA cell lines, indicating a clinical approach for certain patients. The conditional deletion of Usp9x cooperated with Kras(G12D) to accelerate pancreatic tumorigenesis in mice, validating their genetic interaction. We propose that USP9X is a major tumour suppressor gene with prognostic and therapeutic relevance in PDA.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3376394/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3376394/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Perez-Mancera, Pedro A -- Rust, Alistair G -- van der Weyden, Louise -- Kristiansen, Glen -- Li, Allen -- Sarver, Aaron L -- Silverstein, Kevin A T -- Grutzmann, Robert -- Aust, Daniela -- Rummele, Petra -- Knosel, Thomas -- Herd, Colin -- Stemple, Derek L -- Kettleborough, Ross -- Brosnan, Jacqueline A -- Li, Ang -- Morgan, Richard -- Knight, Spencer -- Yu, Jun -- Stegeman, Shane -- Collier, Lara S -- ten Hoeve, Jelle J -- de Ridder, Jeroen -- Klein, Alison P -- Goggins, Michael -- Hruban, Ralph H -- Chang, David K -- Biankin, Andrew V -- Grimmond, Sean M -- Australian Pancreatic Cancer Genome Initiative -- Wessels, Lodewyk F A -- Wood, Stephen A -- Iacobuzio-Donahue, Christine A -- Pilarsky, Christian -- Largaespada, David A -- Adams, David J -- Tuveson, David A -- 13031/Cancer Research UK/United Kingdom -- 2P50CA101955/CA/NCI NIH HHS/ -- CA106610/CA/NCI NIH HHS/ -- CA122183/CA/NCI NIH HHS/ -- CA128920/CA/NCI NIH HHS/ -- CA62924/CA/NCI NIH HHS/ -- K01 CA122183/CA/NCI NIH HHS/ -- K01 CA122183-05/CA/NCI NIH HHS/ -- P50 CA101955/CA/NCI NIH HHS/ -- P50CA62924/CA/NCI NIH HHS/ -- Cancer Research UK/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2012 Apr 29;486(7402):266-70. doi: 10.1038/nature11114.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Li Ka Shing Centre, Cambridge Research Institute, Cancer Research UK, Cambridge CB2 0RE, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22699621" target="_blank"〉PubMed〈/a〉

    An overlapping protein-coding region in influenza A virus segment 3 modulates the host response (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-06-30
    Description: Influenza A virus (IAV) infection leads to variable and imperfectly understood pathogenicity. We report that segment 3 of the virus contains a second open reading frame ("X-ORF"), accessed via ribosomal frameshifting. The frameshift product, termed PA-X, comprises the endonuclease domain of the viral PA protein with a C-terminal domain encoded by the X-ORF and functions to repress cellular gene expression. PA-X also modulates IAV virulence in a mouse infection model, acting to decrease pathogenicity. Loss of PA-X expression leads to changes in the kinetics of the global host response, which notably includes increases in inflammatory, apoptotic, and T lymphocyte-signaling pathways. Thus, we have identified a previously unknown IAV protein that modulates the host response to infection, a finding with important implications for understanding IAV pathogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3552242/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3552242/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jagger, B W -- Wise, H M -- Kash, J C -- Walters, K-A -- Wills, N M -- Xiao, Y-L -- Dunfee, R L -- Schwartzman, L M -- Ozinsky, A -- Bell, G L -- Dalton, R M -- Lo, A -- Efstathiou, S -- Atkins, J F -- Firth, A E -- Taubenberger, J K -- Digard, P -- 073126/Wellcome Trust/United Kingdom -- 088789/Wellcome Trust/United Kingdom -- G0700815/Medical Research Council/United Kingdom -- G0700815(82260)/Medical Research Council/United Kingdom -- G9800943/Medical Research Council/United Kingdom -- MR/J002232/1/Medical Research Council/United Kingdom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Intramural NIH HHS/ -- New York, N.Y. -- Science. 2012 Jul 13;337(6091):199-204. doi: 10.1126/science.1222213.

    Automated design of ligands to polypharmacological profiles (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-12-14
    Description: The clinical efficacy and safety of a drug is determined by its activity profile across many proteins in the proteome. However, designing drugs with a specific multi-target profile is both complex and difficult. Therefore methods to design drugs rationally a priori against profiles of several proteins would have immense value in drug discovery. Here we describe a new approach for the automated design of ligands against profiles of multiple drug targets. The method is demonstrated by the evolution of an approved acetylcholinesterase inhibitor drug into brain-penetrable ligands with either specific polypharmacology or exquisite selectivity profiles for G-protein-coupled receptors. Overall, 800 ligand-target predictions of prospectively designed ligands were tested experimentally, of which 75% were confirmed to be correct. We also demonstrate target engagement in vivo. The approach can be a useful source of drug leads when multi-target profiles are required to achieve either selectivity over other drug targets or a desired polypharmacology.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3653568/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3653568/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Besnard, Jeremy -- Ruda, Gian Filippo -- Setola, Vincent -- Abecassis, Keren -- Rodriguiz, Ramona M -- Huang, Xi-Ping -- Norval, Suzanne -- Sassano, Maria F -- Shin, Antony I -- Webster, Lauren A -- Simeons, Frederick R C -- Stojanovski, Laste -- Prat, Annik -- Seidah, Nabil G -- Constam, Daniel B -- Bickerton, G Richard -- Read, Kevin D -- Wetsel, William C -- Gilbert, Ian H -- Roth, Bryan L -- Hopkins, Andrew L -- 083481/Wellcome Trust/United Kingdom -- BB/FOF/PF/15/09/Biotechnology and Biological Sciences Research Council/United Kingdom -- BB/J010510/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- MH082441/MH/NIMH NIH HHS/ -- R01 DA017204/DA/NIDA NIH HHS/ -- R01 MH061887/MH/NIMH NIH HHS/ -- U19 MH082441/MH/NIMH NIH HHS/ -- WT 083481/Wellcome Trust/United Kingdom -- England -- Nature. 2012 Dec 13;492(7428):215-20. doi: 10.1038/nature11691.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biological Chemistry and Drug Discovery, College of Life Sciences, University of Dundee, Dundee DD1 5EH, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23235874" target="_blank"〉PubMed〈/a〉

    Passenger deletions generate therapeutic vulnerabilities in cancer (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-08-17
    Description: Inactivation of tumour-suppressor genes by homozygous deletion is a prototypic event in the cancer genome, yet such deletions often encompass neighbouring genes. We propose that homozygous deletions in such passenger genes can expose cancer-specific therapeutic vulnerabilities when the collaterally deleted gene is a member of a functionally redundant family of genes carrying out an essential function. The glycolytic gene enolase 1 (ENO1) in the 1p36 locus is deleted in glioblastoma (GBM), which is tolerated by the expression of ENO2. Here we show that short-hairpin-RNA-mediated silencing of ENO2 selectively inhibits growth, survival and the tumorigenic potential of ENO1-deleted GBM cells, and that the enolase inhibitor phosphonoacetohydroxamate is selectively toxic to ENO1-deleted GBM cells relative to ENO1-intact GBM cells or normal astrocytes. The principle of collateral vulnerability should be applicable to other passenger-deleted genes encoding functionally redundant essential activities and provide an effective treatment strategy for cancers containing such genomic events.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3712624/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3712624/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Muller, Florian L -- Colla, Simona -- Aquilanti, Elisa -- Manzo, Veronica E -- Genovese, Giannicola -- Lee, Jaclyn -- Eisenson, Daniel -- Narurkar, Rujuta -- Deng, Pingna -- Nezi, Luigi -- Lee, Michelle A -- Hu, Baoli -- Hu, Jian -- Sahin, Ergun -- Ong, Derrick -- Fletcher-Sananikone, Eliot -- Ho, Dennis -- Kwong, Lawrence -- Brennan, Cameron -- Wang, Y Alan -- Chin, Lynda -- DePinho, Ronald A -- 3 P01 CA095616-08S1/CA/NCI NIH HHS/ -- 57006984/Howard Hughes Medical Institute/ -- P01 CA095616/CA/NCI NIH HHS/ -- P01CA95616/CA/NCI NIH HHS/ -- T32-CA009361/CA/NCI NIH HHS/ -- England -- Nature. 2012 Aug 16;488(7411):337-42. doi: 10.1038/nature11331.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Genomic Medicine, University of Texas MD Anderson Cancer Center, Houston, Texas 77030, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22895339" target="_blank"〉PubMed〈/a〉

    Deregulated MYC expression induces dependence upon AMPK-related kinase 5 (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-03-31
    Description: Deregulated expression of the MYC oncoprotein contributes to the genesis of many human tumours, yet strategies to exploit this for a rational tumour therapy are scarce. MYC promotes cell growth and proliferation, and alters cellular metabolism to enhance the provision of precursors for phospholipids and cellular macromolecules. Here we show in human and murine cell lines that oncogenic levels of MYC establish a dependence on AMPK-related kinase 5 (ARK5; also known as NUAK1) for maintaining metabolic homeostasis and for cell survival. ARK5 is an upstream regulator of AMPK and limits protein synthesis via inhibition of the mammalian target of rapamycin 1 (mTORC1) signalling pathway. ARK5 also maintains expression of mitochondrial respiratory chain complexes and respiratory capacity, which is required for efficient glutamine metabolism. Inhibition of ARK5 leads to a collapse of cellular ATP levels in cells expressing deregulated MYC, inducing multiple pro-apoptotic responses as a secondary consequence. Depletion of ARK5 prolongs survival in MYC-driven mouse models of hepatocellular carcinoma, demonstrating that targeting cellular energy homeostasis is a valid therapeutic strategy to eliminate tumour cells that express deregulated MYC.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Liu, Lidan -- Ulbrich, Jannes -- Muller, Judith -- Wustefeld, Torsten -- Aeberhard, Lukas -- Kress, Theresia R -- Muthalagu, Nathiya -- Rycak, Lukas -- Rudalska, Ramona -- Moll, Roland -- Kempa, Stefan -- Zender, Lars -- Eilers, Martin -- Murphy, Daniel J -- England -- Nature. 2012 Mar 28;483(7391):608-12. doi: 10.1038/nature10927.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Theodor Boveri Institute, Biocenter, University of Wurzburg, Am Hubland, 97074 Wurzburg, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22460906" target="_blank"〉PubMed〈/a〉
